How to check how many battery cycles is your Apple iPhone battery on

An iPhone battery usually lasts throughout a full workday, but rarely much more than a day, which means that you still need to do the ritual of nightly recharging. Also, just like on most Apple devices, the battery inside iPhones is a Lithium-Ion (Li-Ion) one, meaning that it degrades after time. Battery age is measured in battery cycles, where one cycle is equal to the process of draining and completely filling up the battery once. This can mean that you use up your battery from 100% until the phone is at 0%, or completely dead, or you can drain 55% of that battery one day and 45% the next day, and together, the two days combine for one, complete 100% battery cycle. Now that we know how you get 1 battery cycle count, we need to know how many cycles can an iPhone battery go through before its capacity deteriorates significantly. Apple’s official support page gives the following Li-Ion battery longevity for different products. How long is a battery supposed to last? iPhone – 500 cycles Apple Watch – 1,000 cycles iPad – 1,000 cycles iPod – 400 cycles Macbook – 1,000 cycles Typically it would take about two years – but it could be more or less depending on individual usage – to get to that critical number. When you hit that limit, this means that the Li-Ion battery has degraded to 80% of its full capacity. So how do you check how many battery cycles is your iPhone… [Read full story]
